Modern vehicles have electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (or ‘controllers’) are networked to convey information and output measured and calculated data to each other.
This in-vehicle network is a data goldmine for improved maintenance, measuring vehicle performance and its subsystems, fleet management, warranty, and legal issues, reliability, durability, and accident reconstruction.
The focus of Data Acquisition from HD Vehicles Using J1939 CAN Bus is to direct the reader toward acquiring and correctly interpreting data from the in-vehicle network of heavy-duty (HD) vehicles. The reader will discover how to transform messages to scaled engineering parameters and determine the available parameters on HD vehicles, along with their accurateness and update rate.
Written by two specialists in this field, Richard (Rick) P. Walter and Eric P. Walter, principals at HEM Data, the book provides a distinctive road map for the data acquisition user. The authors offer a transparent and straightforward description of the CAN Bus protocol, plus a review of all 19 parts of the SAE International J1939 standard family. In addition, relevant standards come with tables, graphs, and examples.
Practical applications covered are calculating fuel economy, duty cycle analysis, and capturing intermittent faults. Various diagnostic techniques are compared, including OBD-II, HD-OBD, and World Wide Harmonized (WWH) OBD.
Data Acquisition from HD Vehicles Using J1939 CAN Bus is a must-have reference for those interested in acquiring data effectively from SAE J1939 equipped vehicles.
SAE J1939 to USB Gateway in Plastic Enclosure
The SAE J1939 to USB Gateway utilizes our SAE J1939 ECU Simulator Board With USB Port and embeds it in an enclosure. The SAE J1939 gateway allows you to monitor, simulate, and record any PGN as defined in the SAE J1939-71 Standard but also including diagnostic messages according to SAE J1939-73.
The gateway supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP). It is also supported by an extensive programming interface for Windows and Linux/Ubuntu applications, including full C/C++/C# source code for short time-to-market developments.
The MasterCAN V-Gate module reads messages from an SAE J1587 and SAE J1939 network, filters and merges the data into single SAE J1939 messages, and transfers the processed data via the output CAN Bus interface. The converter is suitable for vehicles and machinery equipped with SAE J1708 (SAE J1587) networks. The device input signals may be: PGNs (Parameter Group Numbers) according [...]
An electronic logging device (ELD) is electronic hardware that is attached to a commercial motor vehicle engine to record driving hours. The driving hours of commercial drivers (truck and bus drivers) are regulated by a set of rules known as the hours of service (HOS). The Commercial Vehicle Driver Hours of Service Regulations vary in Canada and [...]
The TMU Pi3 telematics unit by Autopi (Denmark) utilizes the Raspberry Pi 3 Model A+ SBC, and it connects to in-vehicle CAN Bus networks via the OBD2 port.The device uses the 1,4-GHz Broadcom BCM2837B0 SOC with Cortex-A53 64-bit quad-core processor, including 512-MiB SDRAM and a 32-GiB micro SD card with installed Raspbian Jessie operating system and Autopi [...]
To mention it upfront, I am not suggesting building the best ELD (Electronic Logging Device) solution in the market. Such systems already exist, and while I like the idea of disrupting the market, I deem such an attempt extremely time-consuming, thus expensive, and most likely not worth the efforts. In other words, KEEPTRUCKIN and Samsara [...]
As it turns out, I recently received two inquiries that involved the testing of wireless vehicle bus adapters for FMS and IoT applications, thus requiring the simulation of SAE J1939 data traffic. In one case, the device in question was the Wireless Vehicle Adapter (WVA) by Digi; the second case involved an unspecified IoT device. In [...]
Sierra Wireless has announced their Airlink MP70 router to support analytics and reporting for cloud-based vehicle fleet operations. The Airlink MP70 router enables the communication of SAE J1939 or OBD-II vehicle data to the cloud. The Airlink Management Service – Advanced Reporting and Analytics (Alms Ara) services enable organizations to manage their vehicle fleets using Sierra Wireless’ industry-leading Airlink [...]
Congatec (Germany) introduced their conga-SMX8, the company’s first Smarc 2.0 Computer-on-Module. It was designed for Internet-of-Things (IoT) applications as well as for embedded control systems.These Smarc 2.0 modules with NXP i.MX8 processors, hardware-based virtualization, and resource partitioning are also applicable for stationary and mobile industrial applications including real-time robotics and motion controls. Since the modules support an [...]
